S...@Ed I have fancy magnifiers and stuff in my lab. So unfortunately (or fortunately?), i can quickly rule out simple problems like a solder bridge or a crossed wire. <BR/><BR/>In terms of soldering, I think i'm improving. The FPGA was soldered in a reflow oven, but I had to rework it a bit by hand with a soldering iron. The memory chips were done by hand with an iron, flux, some copper wick and a lot of patience. <BR/><BR/>I'm stalled right now as I wait for some more parts to arrive, but I'm hoping I can now solder the FPGAs by hand as well. We'll see, I guess. <BR/><BR/>I will probably end up redesigning the board eventually, so even if these boards turn out to be a complete failure, I have learned enough with this project to continue moving forward. So that's good, I guess.scottjghttps://www.blogger.com/profile/00865187083873717495noreply@blogger.comtag:blogger.com,1999:blog-705536812493836035.post-75907016969451902702009-04-06T17:06:00.000-04:002009-04-06T17:06:00.000-04:00Wow, that's some A+ soldering there man, I wish I ...Wow, that's some A+ soldering there man, I wish I could do that!<BR/><BR/>Did you run flux over the pins, then just wipe solder over it, or did you use a oven?<BR/><BR/>Also, good luck on getting that second s-ram chip going!<BR/><BR/>(Perhaps one of the red wires you hand-soldered to the chips is shorting a nearby pin, causing the error? Even if you don't think this is the case, it couldn't hurt to check!)<BR/><BR/>-Ed the Nerd ;)Ed the Nerdhttps://www.blogger.com/profile/16425265852360740243noreply@blogger.comtag:blogger.com,1999:blog-705536812493836035.post-53459026392091009122009-04-06T12:46:00.000-04:002009-04-06T12:46:00.000-04:00Reminds me of Blizzard's SNES development station....Reminds me of Blizzard's SNES development station...<BR/>http://i42.tinypic.com/2djdsg9.jpgcreaothceannhttps://www.blogger.com/profile/16452109375295357426noreply@blogger.comtag:blogger.com,1999:blog-705536812493836035.post-67331998882467045762009-04-05T11:38:00.000-04:002009-04-05T11:38:00.000-04:00We are working on a similar project.
